Reacts only to temperature! A maintenance-free, energy-saving explosion-proof temperature control valve that uses no electricity at all!
This is a high-precision temperature control valve using a wax-filled actuator. The actuator utilizes the powerful force generated by the expansion and contraction of the enclosed wax as it changes state between solid and liquid due to temperature. Since it operates without using electricity, it is maintenance-free and excels in reliability and energy efficiency. There are two types of operation: it opens (normal operation) and closes (reverse operation) when the set temperature is reached, and it can be selected from a wide variety of options. 【Features】 ■ Explosion-proof design that requires no electricity ■ Responds only to temperature, unaffected by fluid pressure ■ Operates with high temperature accuracy relative to the set temperature ■ Small operating temperature differential, with a deadband of 5.5°C (2.7°C for freeze prevention valves) ■ A variety of sensing methods available ■ Robust and long-lasting due to integrated structure (tight shut-off with SUS plug and PTFE sheet combination) ■ Fail-safe mechanism included * In the unlikely event of actuator damage, it operates to the safe side (valve open) due to a spring mechanism.

Company information
We, Seal Tech Co., Ltd., entered into a sales agency agreement with FURON Corporation in the United States in June 1987 and began domestic sales of their SPRING ENERGIZED SEAL. Today, there is a growing demand for improved working environments, efficiency, and safety across all industrial sectors. However, even in this technologically advanced era, issues caused by fluid leakage persist, and we feel that the demands are increasing. Through the sale of fluid control equipment, our company has developed as a technical trading company that addresses such troubles and technical challenges, responding to the increasingly sophisticated and diverse needs, and contributing to Japanese manufacturing. To gain even greater trust and assurance from our customers, we obtained ISO 9001 certification on April 24, 2011, and are committed to continuous improvement and maintenance through the thorough establishment and operation of a "Quality Management System." Moving forward, we will continue to adopt a customer-oriented approach and strive to respond accurately and swiftly to our customers' needs through the development of products and technologies. We sincerely ask for your continued support and patronage.
